Canada #260 20c Chocolate Corvette 1942-1949 War Effort Issue - Specialized Group of 3 VF NH Stamps, Various Papers and Gums

Sold out

A beautiful specialized grouping of 4 very fine NH (VF-75 to VF-84) stamps covering some of the paper, shade, gum and printing varieties of the 20c chocolate corvette stamps of the 1942-1949 War Effort issue, showing three different printings.

As explained in the blog article here, this issue exists with a variety of different papers and gums as well as some subtle differences in shades. I'm not sure why Unitrade does not list any of these, because they are fairly easy to see, once you know what to look for. 

This lot includes some, but not all of the varieties that exist.  In terms of papers, generally you can find:

  1. A white paper that is soft, that from the back shows fine vertical mesh and especially when held up to a strong backlighting source. 
  2. A cream paper that is still soft, but thicker and which shows some horizontal weave on the back, and occasionally on the front.
  3. A cream paper that is similar to #2, but does not show the horizontal weave.
  4. A crisp greyish wove paper that shows no clear mesh.

In terms of gum, there are at least six types, possibly more. Some study will be required to establish whether these were used in succession over the life of the issue or whether they were used concurrently throughout the life of the issue. Looking at the gum types on the previous issue, the 1937-1942 Mufti issue, and the subsequent issue, the 1949-1953 Postes Postage issue there is some evidence to suggest that they follow a sequence throughout the life of the issue. The types usually seen, which may or may not be found on more than 1 paper type are:

  1. A white or colourless smooth gum, that has a slight level of very fine surface crackling. 
  2. A smooth, shiny cream coloured gum.
  3. A deeper, smooth and somewhat shiny gum
  4. A deep yellowish, smooth gum that is somewhat shiny. 
  5. A brownish gum that is smooth and shiny.
  6. A mottled brownish cream or cream coloured gum with a satin sheen.

In terms of shades. the varieties are subtle, but with careful comparison, you can usually spot some clear differences. The best way to see these is to compare the two stamps and relax your overall gaze and look at the overall appearance of the stamp. If you do this you will generally see some differences in brightness or tone of the colours. This is especially the case with the 3c rose purple and 5c blue.

The stamps included in this lot are:

  • Dull chocolate brown on translucent vertical wove with yellowish smooth gum that has a semi-gloss sheen.
  • Pale chocolate brown on smooth vertical wove that has cream gum that s smooth and has a satin sheen.
  • Chocolate brown on soft vertical wove paper showing coarse vertical mesh, and with cream gum that has a semi-gloss sheen.

The Unitrade catalogue value of the stamps in this lot is $67.50. A wonderful opportunity to start a new specialized branch of your collection with an issue that you may not have given much thought to before. This is easily one of my favourite issues, in terms of how much scope it offers. It is truly incredible when you consider the booklets, the officials, plate blocks and postal history.
